I am trying to discover the ibeacon. i am running app on iPhone 4s. device bluetooth is turned on. beacon is also discovering in other iOS apps. When i am searching for services following delegate "centralManagerDidUpdateState" gets called and State is "On" after this nothing happens. It is expected that "didDiscoverPeripheral" should get called but nothing happens. What wrong i am doing here?
